Description

. Eilipsenzirkel. Ellipsenzirkel mit einer auf dem festen Schenkel verstellbaren Führungsschablone für den Fahrschenkel sind bekannt. Gegenstand der vorliegenden Erfindung ist nun ein gleicher Zirkel, bei dem aber die Schablone noch mit Kerben versehen ist, mit denen, eine ain Fahrschenkel angelenkte Schneide in Eingriff gebracht werden kann, um auf diese Weise die Ellipse nach Wunsch einteilen zu können.. Ovoid circle. Elliptical compass with one on the fixed leg adjustable guide template for the driving leg are known. Subject of present invention is now the same compass, but in which the template is still is provided with notches, with which a cutting edge hinged on the driving leg in Intervention can be brought about in order to divide the ellipse as desired to be able to.

Die Zeichnung läßt den Zirkel in einem Ausführungsbeispiel erkennen, und zwar zeigt Abb. 1 den Zirkel in Ansicht, teilweise im Schnitt und Abb. 2 die Führungsscheibe.The drawing shows the compass in one embodiment, namely Fig. 1 shows the compass in view, partially in section and Fig. 2 the Guide washer.

x ist der Einsatzschenkel des Zirkels mit den beiden Spitzen 2 und 3 ; q. ist das in diesen Schenkel geschnittene Schraubengewinde, auf das die Ellipsenscheibe 5 aufgedreht wird. Die letztere kann in jeder gewünschten Höhe durch einen Keil 6 festgehalten werden, welcher sich in eine Nut 7 des Schenkels 1 bzw. der Scheibe 5 einschieben läßt. Diese trägt am Rande einen `'Wulst 8, um' den eine Klaue g greift, an der, um Bolzen 1o drehbar, der Schlitten 11 befestigt ist, welcher frei verschiebbar auf den am Drehknopf 12 drehbar angebrachten zweiten Fahrschenkel-i_3 geschoben ist. Unten an diesem Schenkel ist in bekannter Weise das wiederum drehbare Einsatzstück 14 vorgesehen. 15 ist die an dem Schenkel 13 drehbar angebrachte Schneide, welche in die Kerben 16 der Scheibe 5 eingesetzt werden kann, um den Schenkel 13 ganz nach gewünschter Einteilung der Ellipse festzuhalten.x is the insert leg of the compass with the two tips 2 and 3; q. is the screw thread cut into this leg onto which the elliptical disk 5 is turned up. The latter can be at any desired height by means of a wedge 6 are held, which is in a groove 7 of the leg 1 or the disc 5 can be inserted. This has a 'bead 8' on the edge around which a claw grips, on which, rotatable about bolts 1o, the carriage 11 is attached, which is freely displaceable pushed onto the second leg-i_3 rotatably attached to the rotary knob 12 is. At the bottom of this leg is the turnable insert piece in a known manner 14 provided. 15 is the cutting edge rotatably attached to the leg 13, which can be used in the notches 16 of the disc 5 to the leg 13 according to to hold the desired division of the ellipse.
